Why do studies show different associations between intrauterine exposure to maternal smoking and age at menarche?
Sign Up to like & getrecommendations! Published in 2018 at "Annals of epidemiology"
DOI: 10.1016/j.annepidem.2018.01.004
Abstract: PURPOSE Studies suggests that intrauterine exposure to maternal smoking both accelerates or delays age at menarche. We hypothesize that these opposing findings relate to different infant and childhood growth patterns across cohorts. METHODS Using data… read more here.
